End 82 of shaft 64 may thenbe raised to its FIG. 4 position by the engagement of leg 118 and a clip162, which is provided on the upper end 164 of rib 100, with circulardiscs 166, 168, respectively, carried by shaft 64 and disposed on theupstream and downstream sides of wall 24, respectively.

The electrical circuit to motor 38 will now be described in connectionwith FIGS. l and 2. A buss bar 170 is connected to battery door 46 by arivet 172 and includes end 184 staked to Wall 14 by a rivet 186 whichalso maintains electrical communication between a rst motor lead 188 andcontact'182. Movable contact 136 is also staked to wall 14 by a suitablerivet (not shown) which also establishes electrical communicationbetween a second motorv lead 190 and contact 136.

Referringnow to FIGS. l, 3 and 4, the appearance of housing 12 may beenhanced by providing it with a simulated control knob 192 and simulatedventilation louvres 194 formed integrally with walls 16 and 14,respectively.

Referring now to FIGS. l, 6 and 7-10, liquid dispensing cartridge 92includes a housing 196 having an encompassing side wall 198 (FIGS.9-11), an open top 200 and an open bottom 202. A vertical partition 204divides housing 196 into an acid-storage chamber 206 and abonding-agent-storage chamber 208 communicatingwith open bottom 202through outlet ports 210, 212-, respectively. Open bottom 202 is closedby a nozzle" assembly 214 having a anged top portion 216, (FIGS.'9 and10) engaged in open top 202. Nozzle assembly 214 includes a pair ofdischarge nozzles 218, 220having outlet ports 222, 224, respectively,forming annular valve-seats 226, 228 upon which check valves 230, 232,respectively, normally seat under the influence'of compression springs234, 236 which encompass valve stems 238, 240 which, in turn, arereciprocably mounted in hollow bosses 242, 244 provided on a horizontalpartition 246- in which outlet ports 210, 212 are provided. Springs 238,240 each includes an upper end 248 bearing against partition 246 and alower end 250 bearing against van annular shoulder 252 provided on anassociated one of the valves 230, 232. Nozzle assembly 214 is providedwith astop 4member 254 engageable with a work piece 256 as it travelsalong base plate 36 in the direction of arrow 258, to control the amountvalves 230, 232 open when they bottom-out on work piece 256, and totarnp work piece 256 sothat the bonding composition will soak through itfaster. 1

Cartridge 92 includes a cover 258 (FIGS. 6 and-11) having a lirstportion 260 covering chamber 206. anda second portion 262 coveringchamber 208 (FIG. 1l). The portion 2162 which covers chamber 208 isprovided with an air vent 264 and a depending` skirt 266 whichencompasses vent 264. A flexible air sack 268 may be attached to skirt266 for receiving air throughwent 264 for equalizing the pressure whichexists outside cartridge 92 and a bonding agent 270, which is stored inchamber 208. A suitable acid may be stored in chamber 206 forcoagulating the bonding agent after it has been dispensed through valve230. Air for pressurizing chamber 206 is drawn in through valve 232 eachtime it is unseated. In practice, it was found to be impractical topressurize chamber 208 by drawing air in through valve 230 becausefreshly-dispensed acid was also sometimes drawn into chamber 208 throughvalve 230 causing the bonding agent 270 to coagulate and plug-up valve230. I y

Referring now more in particular to FIGS. l and 6, cartridge 92 ismounted in a cartridge-receiving chamber 272 formed by wall 24 and acover member 274, which is retained in position on housing 12 by aperipheralange 276 and a hollow boss 2718 which, in turn, engages a pin280 carried by wall 24. Chamber 272 may be closed by a door 282swingably connected to wall 24 and cover member 274 by suitable pins,like the one shown at 284 for the cover member 274. Cartridge 92 isreciprocated within chamber 272 by crank 88 which Works within-a slot286 formed by upper and lower horizontal ribs 288, 290, respectively,carried by cartridge 92. kCartridge 92 also carries a pair of upperfront and rear pins 292, 294, respectively, a pair of front, lower pins296,298 anda pair of rear, lower pins 300,- 302 (FIG. 5) which properlylocate cartridge 92 within chamber 272 and guide it during reciprocationthereof by crank 88: Pin 294 rides in a slot 304 formed by a pair ofvertical ribs 306, 308 carried by cover member 274; pin 302 rides in aslot 310 provided by a pair of vertical ribs 312, 314 carried by covermember 274; pin 292 is prevented from movin-g in a lateral directiontoward front wall 16 by a vertical rib 316 carried by wall 24; pin 29-6is prevented `from moving laterally in the direction of front wall1f6fbya vertical rib 318 carried by wall 24; and pini298 is preventedfrom moving laterally in the direction of rear wall 14 by a vertical rib320 carried by cover memb'et274. Ribs 306 and 312 are joined together bya horizontal rib 322 and vertical ribs 312, 318, are provided withopenings324, 326, respectively, so that pin 294 may ride `lalong rib322.. while pins 302, V296 pass through openings 324, 326 and pin 292passes over the upper edge 328 of rib 3,16 during the positioning ofcartridge 92 in chamber 272. l

...Cartridge 92 vmay be swung to the position shown in broken lines inFIG. 6 when it is desired to service valves 230,v 232Y by moving pin29,8 yalong a horizontal rib 330', which is provided oncover member`274, until pin 298 engages vertical rib 314.

s `Referringnow to FIGS.V1`, 3, 5, 7 and 8, presser foot assemblyw90includes a lower end 336 which carries a pair orarcuatefeet 338, 340each having a serrated edge 342 mounted directly above an associated oneof a pair of rollers 344, 346 rotatably mounted in housing 12 on a shaft348 journalled in vertical partitions 36A, 36B. An intermediate portion350 of presser foot assembly 90 (FIGS. l, 7 and `8) is prevented frommoving laterally by housing member 34 so that crank journal 84 willcause feet portions 338, 340 to travel the path defined by arrows 352 inFIG. 5 when crank 84 rotates in the direction of arrow 354. If controllever assembly 96 is then lowered to lower end 82 of crank shaft 64,feet 338, 340 will press work piece 256 against rollers 334, 346 andmove the work piece 256 in the direction of arrow 258. v Referring nowto FIGS. 12-15, work piece 256 may comprise first and second plies 354,356 of a suitable cloth material upon which a cardboard template 358 maybe placed. Template 358 includes suitable elongated openings 360 throughwhich a pencil 361 may be inserted to trace the location of areas 360A(FIG. 13) to receive the bonding agent 270 and the acid material fromcartridge 92. Template 358 may also be used to trace a pattern 362 (FIG.13) onto work piece 256. Work piece 256 may then be placed on plate 36and rollers 344, 346 beneath feet 338, 340 which may be lowered intoengagement therewith by releasing lever assembly 96. This also energizesmotor 38 causing cartridge 92 and presser foot 90 to reciprocate in sucha manner that cartridge 92 is traveling downwardly, as indicated byarrow 364 in FIG. 8, while feet 338, 340 are traveling upwardly, asindicated by arrow 366. Each time feet 338, 340 reach the lowermostposition of their stroke, as Yshown in FIG. 7, they move work piece 256in the direction of arrow 258, as indicated schematically in FIG. 5.Each time valves 230, 232 reach the bottom of their stroke, as shown inFIG. l0, they deposit drops of bonding agent 270 and the acid containedin chamber 206 to form a line of bonding composition 368 to bond theplies of 354, 356 together along the areas 361. AThe acid coagulates thebonding agent 270 causing rubbery, stringy fibers to entangle themselvesin which the fibers of plies 254, 256 firmly bonding them together.Pattern 362 may then be cut from work piece 256 and turned inside out tohide the seams formed by the bonding composition 368.

The bonding agent 270 may comprise any suitable latex wherein a solid,rubbery phase is dispersed in water to form an emulsion having a pH ofabout 10-11 to prevent the solids from coagulating. A suitable acid,such as citric acid, may then be used in chamber 206 to coagulate thesolids as soon as they are dispensed from chamber 208 onto work piece256 so that rubber stringers are formed when the latex is coagulated bythe acid and these stringers go through the fibers and wrap around themt0 bond plies 254 and 256 together. A typical formulation for thebonding agent 270 is 100 parts by weight of natural rubber latex, 2parts by weight of an anti-oxidant, such as a modified phenol and 0.2parts by weight of a fungistat, such as potassium sorbate. A typicalformulation for the coagulant is 100 parts by weight of water, 5 partsby weight of citric acid and 0.5 parts by weight of a suitablefungistat.

In practicing the present invention, plies 354 and 356 of suitablematerial, such as cloth, may be placed together as shown in FIG. 12 andtemplate 358 may be placed thereon. Pencil 351 may thenbe usedI totracethe pattern as shown in FIG. 13 at 352 and to identify the area 306Awhich should `receive theA bonding material. Work piece 256 may then beplaced on plate 36 beneath feet 338, 340 (FIGS. 7 and 8) and leverassembly 96 may be released from latch 116 (FIG. 4) so that spring 146will move the end 82 of shaft 64 downwardly to the position indicated bycenter line 370 invFIG. 5. Assuming that the shaft 64 waspreviouslyrotated to the position shown in FIG. 5, the center line ofcrank 84, which carries presser foot assembly 90, will -be at thelelevation indicated by center line 372 and crank 88 for cartridge 92will be at the position indicated by center line 374. v

The lowering of lever 96 swings switch crank 126 to the position shownin FIG. 2 lowering movable contact 136 to a closed position so thatmotor 38 is energized. Shaft 64 then rotates in a counterclockwisedirection, as indicated by arrow 376 in FIG. 5, causing presser footcrank 84 to reach the lowermost point of its travel and start upwardlywhile cartridge 92 starts downwardly during rotation of shaft 64 about acenter of rotation defined by line 378.

Each time stop member 254 (FIG. l0) bottoms out on work piece 256,valves 230, 232 will open sufficiently t0 discharge a drop or globule ofbonding composition 368. Work piece 256 is guided over rollers 344, 346until all areas 360A are covered with bonding composition 368. Leverassembly 96 may then be elevated and engaged on latch 116. Work piece256 may then be removed from plate 36 and pattern 362 may be cut outfrom work piece 256 and turned inside out to provide a finished article,as indicated at 362A in FIG. 15.
